Versuchsvorschrift
2.6 g (7.2 mmol) 4-(5,6-dichloro-2-methylamino-pyrimidin-4-yl)-piperazine-1-carboxylic acid tert-butyl ester was deprotected at 10° C. using 100 ml ethylacetate saturated with gaseous hydrochloric acid. After 4 hours the precipitate was filtered giving the title compound (2.4 g, 100%), melting at 204-209° C.
